I used to buy a lot of DVDs, but since I split my time between the US and Europe, I found that half my discs wouldn't play on my Powerbook. Apple only lets you switch regions five times (though the studios actually say you're allowed to do this 25 times -- Apple actually imposes more restrictions than it has to), so I quickly ran out of region-switches and just gave up on DVDs for a while.
